we shouldn't take users so deep into the settings IA because it's easy
to feel lost in settings after clicking on a result without additional
context.
Bug: 143055215
Test: robotest & manual
Change-Id: I337cb5ead31e1e4e7bf9be78132e90630f83ee43
Parent preference previously didn't have a summary
Moved summary test to PreventRingingParentPreferenceControllerTest
Test: PreventRingingParentPreferenceControllerTest.java
Change-Id: I2891e1ccffc4ea8007c8bd25689f242ee34c652c
The full page verion of prevent ringing is still searchable.
- Created a new controller for parent entry.
- On the child controller, inherit the same getAvailabilityStatus() but
override AVILABLE_UNSEARCHABLE to AVAILABLE so it becomes searchable.
